Kitchen Cabinet Problems — and How to Fix Them

Doors that will not stay shut, screws that spin, a gap at the wall, a box that is out of level. Every one has a fix — and an order to try them in.

🔧 Screwdriver jobs first⏱ Most take minutes⚠ And what to hand off

Something has gone wrong, or it is about to. That is normal — every kitchen, DIY or trade-installed, throws up two or three of these. What separates a good result from a frustrating one is knowing the order to try the fixes in, because the cheap causes are almost always the real ones and the expensive theory is almost always wrong.

01 Doors

The door won’t stay closed — or the gaps have wandered

What they search at midnight “cabinet door won’t stay closed / uneven cabinet door gaps” — four causes, and the first one is free.

Work them in this order, because that is the order of how often they are actually it:

  • Loose hinge screws. Around two thirds of doors that creep open are just this. Snug them by hand with a screwdriver — an impact driver is how they get stripped
  • A screw that spins forever. The hole is stripped. Fix the hole, not the screw — see the next section
  • Depth adjustment. Screws tight and it still drifts open? The door is sitting too far off the box for the soft-close or the hinge spring to grab. Wind it in on the depth screw, a quarter-turn at a time
  • A dead hinge. Old spring hinges do lose their snap. A like-for-like replacement with the same 35 mm cup and the same plate is a two-minute job

A genuinely warped door or a box swollen with moisture does happen — but it is the last thing to suspect, not the first. If the four checks above come up clean, sight along the closed door: a warped door will show light at one corner only.

Gaps that wander across a run

When the reveals between doors run wide at one end and tight at the other, resist the urge to chase them door by door. Square each door to its own box first, then walk the run evening the gaps between doors — and remember it is always easier to move one door than two. If no amount of adjusting straightens the line, the problem is not the doors: a cabinet is out of level, and that is a different fix.

02 Fixings

The screw just spins, and nothing tightens

What they search at midnight “stripped screw hole particleboard cabinet” — whatever you do, don’t reach for a fatter screw.

A stripped hole in particleboard is the single most common repair in a kitchen, and there is one instinct to suppress: do not go up a screw size. A thicker screw crushes more of the board it is supposed to grip, and buys you one more turn before it fails again, in a bigger hole.

  • Small hole (a hinge plate, a slide): push in two or three toothpicks dipped in wood glue, snap them flush, and drive the original screw straight back while the glue is still wet
  • Bigger hole: clean it out, pack it with epoxy wood filler or glue in a hardwood dowel, let it cure fully, then drill a fresh pilot
  • The prevention is the same lesson: hinge and slide screws go in snug by hand. Every stripped hole in a new kitchen was made by an impact driver
A wall cabinet that has started to sag off the wall

Stop loading it and check the fixing before anything else. Wall cabinets carry roughly 30–50 lb per linear foot when they are screwed into studs — and almost nothing when they are screwed into drywall alone. Take the doors and the contents off, re-drill into the actual studs with #10 × 2½–3″ washer-head cabinet screws, two per stud through the mounting rails, and use heavy-duty toggles only where a stud genuinely does not exist. A sagging wall cabinet is not a cosmetic problem.

03 Drawers

Drawers that stick, sag, or refuse to soft-close

Three suspects, and you can test all three in a minute. Debris in the runner — wipe the slides clean, front to back. A jammed damper — if the drawer was slammed or dropped, the little hydraulic piston can stick compressed and the drawer stops an inch out; pull it back out by hand to release it. Alignment — undermount runners are screwed through oval holes for exactly this reason: loosen them, square the drawer, re-tighten.

If the drawer front tilts down as it comes out, the box is not sitting fully on the runners — pull it right out and re-seat it until both front clips click. A drawer that binds only when it is full is telling you something else: check that the cabinet is still level and square, because a racked box narrows the opening at the top.

The drawer hits the handle on the cabinet beside it

The classic corner clash, and it has three fixes in order of cost: swap the offending front to a knob or a low-profile pull; move the pull further from the corner (a vertical pull on a drawer front is perfectly normal); or fit a 3″ corner filler so the drawer starts clear of the return. On a drawing this costs nothing — which is exactly why corner fillers exist, and why every inside corner is worth checking while you are still planning.

04 Gaps & level

A gap at the wall, and a cabinet that is out of level

What they search at midnight “gap between cabinet and wall” — the wall is bent. Every wall is bent.

A bow of ¼″ over eight feet is completely ordinary, and the gap it leaves is not a mistake — it is the whole reason fillers and scribes exist. Close it in this order: shim behind the cabinet at the stud lines so the box stays square when the screw comes tight, then cut a filler or scribe molding to the wall’s actual contour with a compass. The one thing you must never do is drive the screws hard to pull the cabinet back against the wall. That racks the box, and every door above it goes crooked — you will spend an hour chasing hinge adjustments for a problem that is not in the hinges.

If a box is genuinely out of level and it is already installed, what you can do depends on one thing: whether the countertop is on.

  • Countertop not yet fitted: back out the wall screws and the screws to the neighbour, reset the adjustable feet, re-clamp the fronts flush, refasten. Ten minutes
  • Stone top already bonded down: the box is staying put. Fix what the eye actually reads — re-adjust the doors so the reveals run straight, add scribe molding where the cabinet meets the wall, and re-scribe the toe kick along the floor

Both answers argue for the same habit, and it is the single most useful one on install day: check level after every single box, not at the end of the run.

05 Surfaces

Chips, scratches, and edges that have swollen

Match the repair to the damage, and be honest about which one you have.

  • Surface scratch, paint or laminate: a touch-up marker or the manufacturer’s touch-up paint, applied with a fine brush in thin coats, left slightly proud and levelled once fully dry
  • Chip on an edge: fill first — a wax fill stick for something shallow, coloured epoxy filler for anything deeper — then colour on top. Filling after colouring never looks right
  • Thermofoil lifting at an edge: this is heat damage, not wear — usually from a kettle, a toaster or an unvented dishwasher venting straight up onto the door above. It will not glue back reliably; the honest fix is a replacement door, plus dealing with the heat source
  • A swollen bottom edge inside the sink base: water has been sitting there, probably for months. Dry it out completely, find and fix the leak, and fit a sink-base mat so the next drip never touches the board
Order the touch-up kit with the kitchen

Matching a door colour two years after the fact is genuinely hard — batches drift, and finishes age. A touch-up marker or paint pen bought at the same time as the cabinets costs almost nothing and will still be an exact match when you need it, which will be about a week after everything is finished.

06 It won’t fit

The appliance, the outlet, and the vent

The dishwasher will not go in. A standard opening is 24″ wide × 24″ deep × 34½″ high, and height is usually the culprit. Wind the machine’s own levelling feet all the way down; check whether new flooring laid over old, or a thick countertop underlayment, quietly ate your clearance; and pull the top panel off if it has one, which is worth about ½″. If the opening is too narrow, note that a frameless box gives you nothing to shave — so the fix is at the cabinetry: re-cut the filler, or shift the neighbouring cabinet.

There is an outlet behind the cabinet. It has to be moved, and by an electrician — an electrical box may not be enclosed and made inaccessible. This is not a corner to improvise in.

There is a floor register under the run. Do not simply leave it blowing into the void under the box: you get dust, condensation, and a warm cupboard. Duct it out to a toe-kick grille with a toe-kick duct kit, or have the register relocated before the cabinets land.

All three are plan-stage decisions that turn into lost days when they are discovered on install day. Ten minutes with the plan and a flashlight before you order is the cheapest insurance in the whole project.

07 Know when to stop

The problems that are not yours to fix

Almost everything on this page is a screwdriver job. These are not, and the cost of getting them wrong is not measured in cabinets:

  • Anything gas. No exceptions, no “just to see”
  • Water under pressure — supply lines and valves. A drain trap you can do; a supply line that lets go while you are out is a floor and a ceiling
  • 240-volt circuits and any new circuit — ranges, ovens, and anything that needs a new run back to the panel
  • Moving an outlet — cheap for an electrician, and it is on the permit and the insurance if it ever matters
  • Stone countertop cutting or re-fitting — a cracked slab is not repairable, and you cannot re-order half of one

Handing those five over is not a failure of DIY nerve. It is the same call the trade makes, for the same reason.

Straight answers

Why won’t my cabinet door stay closed?+

Nearly always one of four things, in this order: loose hinge screws (roughly two thirds of cases), a stripped screw hole if a screw spins without gripping, a depth adjustment that leaves the door too far off the box for the soft-close or spring to grab, or a worn-out spring hinge that needs replacing. A warped door is real but uncommon — check it last.

How do I fix a screw hole that has stripped in particleboard?+

Never go up a screw size — a thicker screw crushes more board and buys you one more turn. Small hole: two or three glue-dipped toothpicks pushed in, snapped flush, and the original screw driven straight back while the glue is wet. Larger hole: epoxy wood filler or a glued hardwood dowel, cured fully, then a fresh pilot hole.

Why is there a gap between my cabinet and the wall?+

Because the wall is not straight — ¼″ of bow over eight feet is completely normal. Shim behind the cabinet at the stud lines so the box stays square when you tighten, then close what is left with a scribed filler or scribe molding. Never drive the screws hard to pull the cabinet back to the wall: that racks the box and every door above it goes crooked.

The cabinet is already installed and it is out of level — can I still fix it?+

Before the countertop goes on: yes, and quickly. Back out the wall screws and the screws to the neighbouring cabinet, reset the adjustable feet, re-clamp the fronts flush and refasten. After a stone top is bonded down: the box is staying where it is, so correct what the eye reads — re-adjust the doors so the gaps run straight, add scribe molding at the wall, and re-scribe the toe kick.

My drawer hits the handle on the cabinet beside it.+

The classic corner clash. Cheapest fix first: swap that front to a knob or a low-profile pull. Next: move the pull further from the corner — a vertical pull on a drawer front is perfectly normal. Last: fit a 3″ corner filler so the drawer starts clear of the return. On a drawing it costs nothing, which is exactly why corner fillers exist.

Why won’t my soft-close drawer close all the way?+

Three suspects. Debris in the runner — wipe the slides clean. A jammed damper — if the drawer was slammed or dropped, the little hydraulic piston can stick compressed; pull it back out by hand to release it. Or alignment — the runners have oval screw holes, so loosen them, square the drawer, and re-tighten.

How do I fix a chip or a scratch in a door?+

Match the repair to the damage. A surface scratch on paint or laminate takes a touch-up marker or matching touch-up paint, in thin coats, levelled once dry. A chip on an edge gets filled first — a wax fill stick for shallow, coloured epoxy filler for deeper — then coloured on top. On thermofoil, a lifted edge is heat damage; it will not glue back reliably and the honest answer is a replacement door.

My dishwasher will not fit the opening.+

A standard opening is 24″ × 24″ × 34½″, and height is usually the problem. Wind the machine’s own levelling feet all the way down, check whether new flooring or a thick countertop underlayment ate the clearance, and remove the top panel if it has one. Too narrow is a cabinetry fix, not an appliance one — a frameless box has nothing to shave, so re-cut the filler or shift the neighbour.

There is an outlet or a floor vent exactly where a cabinet goes.+

Two different problems. An outlet behind a base cabinet has to be moved by an electrician — boxes may not be enclosed and made inaccessible. A floor register must not be left blowing into the void under a cabinet: duct it out to a toe-kick grille, or relocate the register before the cabinets land. Both are plan-stage calls; found on install day, each costs you the day.

My cabinets arrived damaged or with parts missing.+

Inspect before you sign. Note the damage on the delivery receipt, photograph the pallet, the cartons and the parts from several angles, and report inside the claim window — often about five days. The critical part: do not assemble or install a damaged cabinet, because most claims require it unassembled and building it can end your right to a replacement.

Better than fixing it

Catch it on the plan, not on install day.

Most of the problems on this page start as a decision made three weeks earlier — a corner without a filler, an outlet nobody noted, a run that was never going to be level. Draw the kitchen first and they never happen.
